Exotic Reds & Blues takes a unique approach in delivering not just "reds", but also the powerful "blues and purples", yielding a wide-spectrum of antioxidants. We don't only use common fruits, but instead include many exotic fruits that most people will have a hard time incorporating into their everyday diet. Reds and blues typically get their color from a class of antioxidants known as anthocyanins and carotenoids, but limiting your supplement to just one color of fruit only gives you a fraction of the antioxidants that exist across multiple colored-fruits.
